 # Questions
 
-If you are having difficulties running the app or have a question about the service, please ask a question on [dW Answers](https://developer.ibm.com/answers/questions/ask/?topics=watson) or [Stack Overflow](http://stackoverflow.com/questions/ask?tags=ibm-watson).
+If you are having problems using the APIs or have a question about the IBM
+Watson Services, please ask a question on

+or [Stack Overflow](http://stackoverflow.com/questions/ask?tags=ibm-watson).
 
-# Issues
+# Code
+
+* Our style guide is based on [Google's](https://google.github.io/styleguide/jsguide.html), most of it is automaticaly enforced (and can be automatically applied with `npm run autofix`)
+* Commits should follow the [Angular commit message guidelines](https://github.com/angular/angular/blob/master/CONTRIBUTING.md#-commit-message-guidelines). This is because our release tool uses this format for determining release versions and generating changelogs. To make this easier, we recommend using the [Commitizen CLI](https://github.com/commitizen/cz-cli) with the `cz-conventional-changelog` adapter.

+If you want to contribute to the repository, follow these steps:
+
+1. Fork the repo.
+2. Develop and test your code changes: `npm install -d && npm test`.
+3. Travis-CI will run the tests for all services once your changes are merged.
+4. Add a test for your changes. Only refactoring and documentation changes require no new tests.
+5. Make the test pass.
+6. Commit your changes.
+7. Push to your fork and submit a pull request.

+## Tests
+
+Ideally, we'd like to see both unit and innervation tests on each method.
+(Unit tests do not actually connect to the Watson service, integration tests do.)
 
-1. Fork the repo
-1. Develop your code changes
-1. Ensure `eslint` is happy: `npm run lint`
-1. Ensure the tests pass: `npm test`
-1. Commit your changes
-1. Push to your fork and submit a pull request
+Out of the box, `npm test` runs linting and unit tests, but skips the integration tests,
+because they require credentials.
